You are saying that the 85 weighs ~4,650 lbs, and the 60 weighs ~180 lbs less?

So, you think Tesla designed the 60 kWh model to be heavier just to avoid crash safety testing?

What did Tesla do to the 60 to add the extra weight, put some sandbags in the frunk...?

Yes, yes, and no. The 25kWh battery difference has to weigh more than 180lbs, because otherwise that works out to a pack level energy density of 300wh/kg, which is impossible since the 18650 cells Tesla uses are around 250wh/kg at the cell level, and the pack is around 150wh/kg.

You have the engine power listed in the column now, but if it has the REx engine, then the weight you have is wrong. Maybe nitpicking, but the REx really almost makes it a different car don't you think?

Yes - potentially, one way to handle this. I was going to change BEV heading to BEV(x). In terms of weight etc - those are going to be different even for different trims. I was going to handle the differences by having multiple values in the columns (like I've done for S battery size, foe eg). I'll also indicate in some way what are optional (like the REx).
